Using finite element method,the FSI vibration characteristic of the bent pipe system and the flow characteristics of fluid within the bent pipe system are calculated and analyzed.
由于管道的弹性作用,管道壁面又会反过来影响管内流体流动情况,两者之间存在复杂的耦合作用;弯管内侧壁附近能量损失较大,静压分布从0~°90°截面始终是外侧高于内侧,进口段湍动能较小、拐弯处较大,管道内流体流速在弯曲管道转角处相对较高。
As an example, the results of 3-D turbulent incompressible flow in 90° curved duct with strong curvature are presented.
作为算例，本文给出了三维９０°强曲率弯曲管道中气流的不可压缩紊流状态的数值计算结果，并与相关的实验数据进行了对比，结果是满意的。
